Migration of an EEG settlement system to SAP NetWeaver Web AS
Project duration: 9 months
Brief description
Migrating an existing 2-tier application implemented in Java (the application is for the long-term implementation of the system-side tasks of a transmission provider in the context of the amendments to the Renewable Energy Sources Act in the electricity sector from July 21st, 2004 (EEG)) to a J2EE-based n-tier application using the SAP Web Application server.
Supplement

The client receives only the presentation logic (Swing, JDesktop, MVC-Pattern), while the entire business logic is implemented on the server (J2EE). Communication between the client and server is via RMI/IIOP, server-side control of the processing is implemented via stateless session beans. Access to the Oracle database takes place via JDBC in accordance with the existing 2-tier application. The implementation takes place in SAP Basis operation using JDI (Java Development Infrastructure).
Subject description
The application supports the transmission provider in carrying out nationwide balancing control in accordance with EEG in the following tasks: Recording and settling the energy quantities received by the distribution system operators; Horizontal adjustment: Proportionate distribution of the received energy and the reimbursement provided between the transmission providers; Vertical adjustment: Proportionate transfer and settling of the received electricity to power supply companies supplying end consumers.
